Your Users Expect an App. You're Serving a Website.
If you're a product lead watching users bounce when the train goes through a tunnel, you need a PWA -- not another responsive redesign.
We build progressive web apps with service workers, push notifications, and app store presence using Next.js and Workbox.
A progressive web app turns your existing website into something that genuinely behaves like a native app. Users can install it on their home screen, open it offline, and get push notifications -- none of which require an app store download. We handle service workers, Web App Manifest configuration, and caching logic through Workbox. The payoff: faster load times, no download friction, and an experience that holds up whether someone's on fiber or a shaky coffee shop connection.
Your Current Site May Be a Liability
Common gaps we find in nearly every audit.
How We Build This Right
Every safeguard, built in from Day 1.
Service Worker Architecture
Custom service worker strategies -- cache-first for static assets, network-first for API calls, stale-while-revalidate for content pages. Built with Workbox so the caching logic stays maintainable six months from now, not just on launch day.
Offline-First Data Layer
IndexedDB-backed offline storage that queues actions and syncs when connectivity returns. Users can fill out forms, save items, and browse content without needing a live connection.
Push Notification System
Web Push API integration with subscription management, segmented campaigns, and quiet hours. The backend handles VAPID keys and delivery analytics so you're not flying blind on what's actually landing.
App Store Deployment
PWABuilder and Trusted Web Activity packaging for the Google Play Store, Microsoft Store, and Samsung Galaxy Store. One codebase, multiple distribution channels.
Web App Manifest Optimization
A complete manifest with adaptive icons, splash screens, display modes, and share target configuration -- the stuff that actually triggers browser install prompts on qualifying visits.
Background Sync & Updates
Background sync handles failed requests automatically. Skipwaiting and clients.claim strategies make sure users always run the latest version, with no stale cache surprises two weeks after you've shipped a fix.
What We Build
Purpose-built features for your industry.
Precaching & Runtime Caching
Workbox precaches critical assets at install and applies runtime strategies per route for instant navigation.
Install Prompt UX
Custom beforeinstallprompt handling with contextual triggers that convert 3–5x better than the browser's default install banner.
Offline Fallback Pages
Branded offline pages with cached content and search, so users never hit the Chrome dinosaur screen.
Asset Versioning & Cache Busting
Content-hashed cache keys with automatic cleanup when the service worker updates.
Adaptive Loading
The Network Information API detects connection quality and adjusts -- smaller images on 3G, full resolution on Wi-Fi. It's a small thing that makes a noticeable difference.
Analytics Without Network
Offline analytics queue in IndexedDB and replay to Google Analytics or Plausible once connectivity returns, so you're not losing conversion data every time someone goes underground.
Built on a Modern, Secure Stack
Our Development Process
From discovery to launch. Quality at every step.
PWA Audit & Strategy
Week 1We start by auditing your existing site against the Lighthouse PWA checklist, mapping your offline use cases, and figuring out where push notifications actually make sense for your users. Then we implement Workbox-powered service workers with route-specific caching and configure your Web App Manifest -- icons, display mode, scope, all of it.
Service Worker & Manifest Build
Week 2–3From there, we build offline fallback pages, an IndexedDB sync layer, and the full push notification subscription flow with backend delivery infrastructure.
Offline Experience & Push Integration
Week 4–5We generate TWA packages for Google Play and PWABuilder packages for the Microsoft Store, configure digital asset links, and get store listings set up.
App Store Packaging
Week 6Then comes cross-device testing across Android, iOS, and desktop -- offline scenarios, push delivery rates, install funnel conversion. You get 30 days of post-launch tuning included, because something always needs a tweak in the real world.
Testing, Launch & Optimization
Week 7–8A PWA is a web application that combines service workers, a manifest file, and HTTPS to deliver an app-like experience -- installable, offline-capable, and push-enabled. Unlike native apps, PWAs share one codebase across all platforms, skip app store review cycles, and update instantly. Users reach them through a URL or a home screen icon.
